ARM: dts: imx6ull-dhcom: Add DHCOM based PicoITX board
Add DT for DH PicoITX unit, which is a bare-bones carrier board for the DHCOM. The board has ethernet port, USB, CAN, LED and a custom board-to-board expansion connector. For this board a DHCOM i.MX6ULL SoM configuration without WiFi/BT is used. The interface is used for the SD card instead. Make this adjustment by using a separate DT include file.
